How the Maternal Environment and Early Life Shape the Infant Gut Microbiome Pathway(s) and Risk of Disease
from Section II - Exposures Driving Long-Term DOHaD Effects
Published online by Cambridge University Press: 01 December 2022
Maternal and infant microbiota are an emerging target of investigation and have particular relevance to disease, ranging from obesity and diabetes to many immunological disorders. Infant gut microbiome colonization and growth are influenced by environmental stimuli such as mode of delivery, infant diet (breastmilk), antibiotic exposure and maternal characteristics including obesity, diet and gestational diabetes. Alterations to the normal bacterial colonization and maturation of the infant gut microbiota – notably short chain fatty acid producers in the phylum Firmicutes and lipopolysaccharide-producers of the family Gammaproteobacteria – can lead to substantial differences in host-microbe interactions and altered neonatal immune system memory/development. Remodelling these pathways during early life may hold promise for correcting developmental programming of both innate and adaptive immunity associated with insulin resistance, pre-diabetes, obesity, non-alcoholic fatty liver disease and diseases linked to dysregulated immunity in youth, including Type I diabetes, asthma and allergies.
